Abstract
This paper addresses the issue of the information content of a biomet-
ric image or system. We define biometric information as the decrease
in uncertainty about the identity of a person due to a set of biometric
measurements. We then show that the biometric information for a
person may be calculated by the relative entropy D(p q) between the
population feature distribution q and the person's feature distribution
